Firefox Hogging All Resources
Utilitzing 99% CPU Resources

Hello,

I've long been a firefox convert, but recently have developed a problem I can't seem to fix. A problem big enough to leave me here using IE 7 now instead.

Here's what happens. I'll launch Firefox. Surf the web. All works well. And then, out of the blue, Firefox just simply "takes over" all CPU resources. In task manager, it shows anywhere from 95-99% CPU resources being used by Firefox. And Firefox just won't "let go" of these resources, no matter what I try or do, short of shutting down the browser completely.

When Firefox takes over these resources, surfing becomes incredibly slow, painful and my computer operates as one might guess very, very slow.

So my question is, why is Firefox mysteriously taking over my computer resources and not letting them go? What can I do to fix it? I much prefer Firefox to IE, but right now, Firefox is simply killing my "surfing experience."

Jim

I seem to have had this throughout my Firefox life. It usually happens when I have sites open that have Flash ads in them. In fact there are a few bug reports on the Firefox site which usually descend into the Firefox devs blaming Macromedia or should I say Adobe now.

Kinda hoped that Firefox 2 would fix all this but no such luck.

Don't know if this thread will help, but check jdmorgan's post #:3084964 in this thread [webmasterworld.com] . This made a huge difference in the way FF works for me.

I found using the "noscript" extension with FireFox 2.0 seems to have solved the problem, although it now blocks scripts by default. Which I'm discovering isn't such a bad thing overall. :)

Firefox is a RAM hog, easily using 10x as much as IE. To limit RAM usage try a simple config tweak. Set your browser.cache.disk.capacity to a value that fits your total RAM. In the address bar, type "about:config" , then change the following:

* Key: browser.cache.disk.capacity
* Modified Value: Depends on your machine. For RAM between 512BM and 1GB, try with 15000. For RAM between 128MB and 512M, try 5000. Your mileage may vary :)
